This article is a placeholder. The full piece is being written and will replace this text in a later milestone.

The finished article will cover:

• why going from none to some matters more than going from some to more
• the difference between structured exercise and general daily movement
• realistic starting points for people who currently do very little

In the meantime, the FAQ explains which lifestyle factors the calculator uses.
